Abstract
A photovoltaic panel racking system with integrated grounding bars integrated with an extruded integrated rail. The integrated grounding bar enables grounding of photovoltaic panels to a racking system without the use of additional parts or tools. When photovoltaic panels are installed onto an integrated rail, the grounding bars perforate the anodized coating of the frame of the photovoltaic panels to make metal to metal contacts. The grounding bar may be attached to the underside of solar panel frames. Further, an integrated grounding bar rail reduces the number of roof penetration connections necessary for safe grounding of a photovoltaic system. In a ballast mounted photovoltaic panel system, ballast pans may be used to connect the integrated rails between adjacent rows of photovoltaic panels, thereby further reducing the number of grounding points needed to ground the system.
